EDWARD H. MCLOUD, or coLUMBUs'oHIo, Assrevrion fro ITnEIIINEAR'MANUFAG- TUBING COMPANY, 0F COLUMBUS, OHIO, A conroRATIo'N'o'r WEST VIRGINHL AUTOMATIC rlnnfnnsrs'rnvo SHUTTEE.

To all 'whom it may concern.'

Beit known that I, EDWARD H. MGCLOUD7 a citizen of the United States, residing at. Columbus, inthe county of Franklin and State of Ohio, have invented a certain new and. useful Improvement in Automatic Fireis a specification. A

This invention relates more especially to rollers for automatic tire shutters so called that are provided with a normally operative counter-balance member and a thermally controlled tension member opposing the action of such counterbalance member so that upon the' release of the" thermally controlled ten-- sion member the shut-ter is caused to descend and close the opening in which the shutter is installed. i

The object of the invention generally is to improve the details'of construction of such rollers and more particularly among others to provide means for nicely regulating the speedatwhich the shutter shall descend and avoid violence in -the action of the parts.

The invention is embodied in the example herein shown and described, the features ofi novelty being pointed 'out in the appended claims.

In th accompanying drawings Figure 1 is a sectional view taken longitudinally ot' the barrel-'or roller, partsbeing shown in full. In this view the ldisks or tumblers used in the construction are shown in those positions theyoccupy when the shutter is up. Fig. 2'is ,a vienr partly in elevation and partly in section t illustrate details .of the thermally controlled devices, and with slight changes 'in the forms o other parts. lfig. 3 is a sectional view showing the position of Specication of Letters afnt.

In the' views 6 designates the barrel or mental bracket 17 a 'starwheel 2O that is shutter receiving member. The shutter, designated', can be attached either directly to the barrel or to collars' seein-m thereon as r: l v The characters 8 and-.roa designate plugs `fitted` in the opposite ends of the barrel.

The plug 8 which is in elfect a clutch member is provided at its innerside with a lug 8,.and said plug is made circularly ad]ust Paten-tea Dec'. 9, 1913 screws 8c insertible in any of a series of holes 8, 'The plug 8 isl also provided with a number pf holes 8e into one of which one end of a bar orpin can be inserted to facilitate the turning of the plug in its seat in' the end of the barrel;

9 designatesa shaft part. supported in the bracket 10 and extending through' the plug 8l and into the barrel. The shaft part 9 has pinned in`it-s outer end beyond the-bracket a wheel 11 and 12- is adevice for'loeking said wheel and {shaft in the position to which they may be turned. Encircling the' shaft 9 1.-; 'a coil spring 18 secu-red at one endto a.' collar 1-1 pinned on the shaft and at .the other end to a collar 15 secured by screws 15a to the barrel. The collar l5 turns on the shaft 0 and constitutes a supporting-member for the barrel. The function of the .springl or.. tension member 123 is to counterbala-nce the shutter for operation in normal ci'rcum` stances and to hold the shutter in the position to which it may be uncoiled as well as to make its operation easy. The shaft partf) has pinned to its inne-r end a collar 9a.'

1G designates a second shaft part that is supported in-a bracket 17 supplemental to a main bracket l? through which the corresponding end of the barrel extends. Said shaft partv 16 extends through the plug or clutch member 8 and into the barrel, its inner extremity extending rotarily into on'e end of the collar .98.' Encircling theinner portion of the shaft part 16 is a coil spring, or tension member 18 wound in a direction to oppose the action of spring'l. 'The coil spring 1S is secured at one end to the collar D and at its other end to a collar 19 'pinned on the shaft part 1V. rl`he shaft parl: 16 has v :er-.ured in its outer end beyond the suppleengaged by a` pivoled dog 2l on .alongweighted lever fulcrumed 'at 22a, said lever being held up to latch the wheel 20 by a wire containing one-or more links 23 fusible b v' a dangerous -rise of temperature.

The wire 23 is shown as connected to the shorter arm of a lever 211 ulcrumed in a small hanger-'25 on the'ceiling or other fixed part. ed as at 24, so as to insure prompt releasel Said lever has'its longer armweightof the lever 2'2 when one of the fusible links 253i* its-melted. The eollar- 19" has a disklike head or clutch member 19" provided with a 55 part, releasable means for holding the other ii y 1,081,129

19 Ir1" p1actice the *spring 1'3 is' first adjusted. by turning theshftpart 9 until the shutter is counterbal'aneed or supported by that spring in elevatedlposition'after which said shaft. is locked-*from rotation. The shaft partl is then turned to place the spring 1S undertension and so asA toimpelthe shutter downward when actin on the barrel' as 'her'.-inafter described a 'ter which saidshaft .purt is latched bythe thermally controlled. means This lastadjustment'I is made with the shutter entirely` raised. The screws' 8c 'are' .then removed 'andthe-plug 8 turned until all the projections'or lugs from the lug ib to the lug 19" are abutted, as seen in Fig.

l, in. such a way that when the shutter is normally 'lowered the lug 8h'will turn first out of abutmentwit-h' the contiguous lug of' the adjacent disk and then into abutment with the samelug but at its opposite side, As

t the shutter is further lowered the tirst dislr4 picked up a'cts on. the second and so on,- it 'being intended-'that asutiicient number` or' disks'shall be used to ermit theuiecessary turns'of the barrel to e, ect a complete closing ofA the shutter before the last disk operates onthe l'ug 192..; When, however, the shutterbe ilnr- 1n raised position, the shaft part 16 is'au o'matically released bythe thermally controlled. devices the lug '19 irri-.,- 40 pelledby the released spring 1-8 acts througlfii. the disks on the lug 8b, and' counteracts suii-. ciently :the counterbalancing eiect of the spring 13 on the barrel to uncoi'l the shut-ter to closing position, or to permit gravity -to operate with a similar result according to the degree of tensin at which the spring' 18 may havebeendcft.
